The distance from the vertex to the center of curvature is known as the radius of curvature (represented by R). The radius of curvature is the radius of the sphere from which the mirror was cut. Finally, the distance from the mirror to the focal point is known as the focal length (represented by f).

## How do you find the radius of curvature of a spherical mirror?

R=CF+FP. In other words, in the small-angle approximation, the focal length f of a concave spherical mirror is half of its radius of curvature, R: f=R2.

## What is the relation between the focal length and radius of curvature of a spherical mirror?

The relation between focal length (f) and radius of curvature (R) of a spherical mirror is that the focal length is equal to half of the radius of curvature i.e. f=R2.

## Is radius of curvature negative for concave mirror?

By convention, distances are measured, along the central axis, as positive from the mirror in the direction of the object and negative away from the object. Hence the radius of curvature and the focal length are positive for concave mirrors and negative for convex mirrors.

## Is radius of curvature negative?

The distance from the vertex to the center of curvature is the radius of curvature of the surface. If the vertex lies to the left of the center of curvature, the radius of curvature is positive. If the vertex lies to the right of the center of curvature, the radius of curvature is negative.

## What is the radius of curvature of plane mirror?

infinite

## What is the radius of curvature of the mirror its focal length is 20 cm?

The radius of curvature of a spherical mirror is 20 cm. What is its focal length? Therefore, the focal length of the spherical mirror is 10 cm.

## What is the radius of curvature of plane surface?

The radius of curvature of a plane surfaceâ€‹ is infinity. The radius of curvature of a plane mirror is infinity. It can be considered that the plane mirror is a part of infinitely large spherical surface. For a infinitely large spherical surface, the radius of curvature is infinite.

## What is the radius of curvature of plane mirror Class 10?

Hence the radius of the curvature of the plane mirror is infinite.

## What is the radius of curvature and magnification for plane mirror?

So, radius of curvature for a plane mirror will be infinite.

## What is the magnification of plane mirror?

1

## What is the magnification of a plane mirror?

Plane mirrors produce images that have a magnification of 1. In conclusion, plane mirrors produce images with a number of distinguishable characteristics.

## Why is the magnification of a plane mirror 1?

The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object.

## Why is magnification of a plane mirror always one?

The distance of object and distance of image are equal in the case of a plane mirror and the object distance is negative. Which gives us a magnification of +1.

## Which mirror gives a magnification of +1?

Concave mirror can produce image of magnification -1 and convex mirror always made diminished image so its magnification is always less than 1 and plane mirror always produce image of same size so it will produce image if magnification of 1.

## What is the formula for magnification obtained with aliens?

Let’s explore the magnification formula (M= v/u) for lenses and see how to find the image height and its nature (whether it’s real or virtual).

## What is the magnification of a convex mirror?

A convex mirror always creates a virtual image which is diminished. So, magnification produced by convex mirror is always less than one.

## Is focal length of a concave mirror positive or negative?

focal length | object distance | |
---|---|---|

concave mirror | positive | positive |

convex mirror | negative | positive |

converging lens | positive | positive |

diverging lens | negative | positive |

## What is the formula of convex mirror?

Suppose an object is placed u cm in front of a spherical mirror of focal length f such that the image is formed v cm from the mirror, then u, v and f are related by the equation; 1/f= 1/u + 1/v. This equation is referred to as the mirror formula. The formula holds for both concave and convex mirrors.

## What best compares convex or concave mirrors?

Terms in this set (11) Which best compares convex and concave mirrors? Convex mirrors produce only virtual images, and concave mirrors produce real and virtual images. The mirror produces an image that is inverted, real, and smaller than the object.

## Which best describes the surface of a concave mirror?

Which best describes the surface of a concave mirror? It curves inward. It is virtual and behind the mirror. The ray diagram shows a candle that is placed between the focal point and the mirror.

## Which describes the image formed by a convex mirror?

Image Formation By Convex Mirror The image formed in a convex mirror is always virtual and erect, whatever be the position of the object.

## What best describes reflection and refraction?

Which best describes reflection and refraction? In reflection, rays bounce off a boundary, and in refraction, rays pass through a boundary.
